This mechanism is morefully shown in Fig. 6, where G is the key-board and 1 2 3, 850., arekey-heads, lettered as hereinafter explained. These levers G are shownas hinged near the middle, so that the depression of a key-head raisesthe other end thereof. There is no difficulty in hing-ing them at theother end from the lettered key-head, making them levers of the secondorder. It would be merely a mechanical equivalent to make these leversof the third order.

J J are two levers also crossing the levers of the key-board andattached at the ends K K to the movable shaft J Fig. 15, the other endbeing free to move as the levers G are moved. It will be seen that thetransverse levers H H are not hinged at the same end as the levers J J,but at the opposite ends, so that by the movement of the levers G thefree end of H and J describe angular distances differing with each leverG moved, but having a certain relation each to the other. The uses ofthese levers will be described farther on. There is also a roller, L,lying across the levers G and at right angles thereto. The movement ofany one of the levers G moves every part of this roller through the sameangle, its function being to communicate a uniform and definite angularmovement to the bar M, adapted to receive and distribute it, asdescribed farther on. This roller is rigidly attached to the rockingshaft M by the arms h 5 at its ends, so that if any key of the key-boardis depressed the-whole length of the roll L and M moves simultaneously.

.N N, Figs. 3 and 12, are channels or troughs into which the type aredistributed.

0 0, Figs. 3 and 12, are pushers that move forward each type after itfalls through the channels P P. (Shown in Figs. 2 and 3.)

I now proceed to a more particular description of my machine, havingindicated such of its principal parts as are necessary to acomprehension of its general plan.

In Fig. 6 the key-board G is shown with its several keys G. The numberof the keys shown is only sixteen; but this is to enable the draftsma-nto exhibit more distinctly the construction. I use any desired number ofthese keyssay from thirty to thirty-sixdepending on the number ofcharacters 10 be distributed. Vith twenty-six keys I distribute thewhole American case. To do this at least five characters must pass intoeach one of the thirty-six recesses of the receivers in E and E, and thefurther separation must take place at another stage of the journey ofthe letters from their starting-point to their final resting-place inthe channels N N. For example, there are five letters A, large andsmall, in each font and five of a kind of all other letters of thealphabet. All the As pass into one channel and all the Bs into another,and so 011. Besides the twenty-six letters, the figures, marks, andsigns could also pass into some one designated for the pur pose.

Upon depressing a key of the key-board say 2the transverse levers H andJ, Fig. 6, would both be moved through different angular distances.\Vhatever key is depressed different distances will be traversed by thefree end of these levers, because no two levers G act upon them at thesame distance from their fulcrum. The lever H is connected with one armof the right-angled or bell-crank lever I at h, Fig. 15. The other armof this bell-crank lever extends up to 71 where it connects with andgives motion to an arm, 71 on whose spindle is a toothed sector, 71meshing with a small gear, 0*, (shown in Fig. 17,) which is shown, also,in Fig. 5, at B. This pinion is secured to and actuates the roll R, onwhich are pins or teeth R, arranged vertically, as shown at R in-Fig.17. pression of any key-headsay 2will operate the lever I' and by itsconnection cause this cylinder or roll to revolve a certain distance.The movement of any other key-head would move this cylinder through adifferent distance, depending upon the length of the are traversed bythe free end of the lever H. These pins or teeth R or their equivalentsare stops to arrest the movement of the receiver E, Fig. at, or E, Fig.14., when the recess in said receiver has been brought exactly inposition to receive the letter called for by the key depressed. But forthis stop the proper opening in the receiver E might pass by the openingin the channel 0 from which it should receive its type, owing to themomentum of its rapid movement to reach its position. Having, I think,made clear the functions of this transverse lever H and shown itsconnections, I will explain the use and connections of the transverselever J, fixed at one end to the rocking bar J so that the free eiiddescribes an arc varying as different keys are depressed. It will beseen that these transverse levers H and J are hinged at ends oppositewith respect to each other, one on the right hand and the other on theleft. The effect of this is to cause the free end of these levers tomove in arcs having a certain fixed and inverse relation to each other.The depression of any key moves each a definite distance, and thisdistance continually varies, depending upon the proximity or remotenessof the actuating key-lever to the fulcrum of these transverse levers.

The function of the transverse leverJ is towith a bar, J that easily andfreely rotates The deat J, and which bar at J is firmly connected withthe arm J and this, through the connecting-rod J with the movablereceivers E and E, and actuates them, as shown in Figs. 2 and 5. Thepiece E, Fig. 5, is connected with the receiver on the inner face at itslower end near the beginning of the tubes P, and is designed tocooperate with the pins or teeth R of the stop-cylinder R, one of whichpresents itself in front of E to arrest its movement at the right point,as determined by the co-operation of the stop-cylinder mechanismoperated by the key used, as before explained. The transverse bar L,Figs. 3 and 6, is also seen to be moved by the movement of eachkey-lever; but since it is the free portion of a rocking frame whosepivoted side is M, with bearings at M in Fig. (3, its movements arealways through the same are whatever key is depressed, since the pivotedshaft M is parallel with the fulcrum of the keylevers. This bar performstwo different functions:

First. It actuates the mechanism that expels the end type from thechannel G into one of the recesses in E E. This is accomplished asfollows: By the partial rotation of the shaft M, Fig. 6, the lever M ismoved. This lever is connected with the 8.1'11177L2, which at its otherend operates a ratchet, m upon the vertical shaft M so that a movement,as described, of the lever M causes a partial rotation of the uprightshaft M. Attached to this shaft M at its upper end, Fig. at, is aratchet-wheel, C,-whose teeth operate upon the end of the lever F, theopposite end of which lever carries the hammer or pusher F, forexpelling the end type from the opening in the channel 0. This lever F,at its end bearing on the teeth of the ratchet-wheel, is pushed forwardby the rotation of this ratchetwheel, which retracts the opposite end ofthis lever, carrying the pusher or hammer far enough to allow the columnof dead matter in channel 0 to be moved up by the springs S S S throughpusher B, Figs. 2 and 4, causing the end type. to occupy the placevacated by the retracted hammer F, Fig. 4, and to stand in front of itat the instant of the release of the ratchet end of the lever F. As soonas the tooth of the ratchet-wheel in its rotation releases the end ofthis lever F, the spring F Fig. 4, forces the hammer F against the endletter and drives or thrusts it into the recess E in the receiver E,awaiting it, as before explained on the depression of its key by theoperator.

Second. This same bar, L, by its movement operates the pushers O O O toadvance the type as they fall into the channels N N N as hereinafterexplained.

Having, I think, fully described the operation of the key-board and theseveral pieces of mechanism therewith connected and thereby actuated andthe functions of each, I will now explain other parts of the machine,their operation and connection.

The galley A 011 which the dead matter is placed, may be horizontal orpreferably inclined at such an angle that gravity will feed the deadmatter down as line by line is cut off and pushed forward in the channelC by the pusher-bar B, Fig. 1; or, it this galley be horizontal, themat-ter may be pushed forward by any convenient means, as by a weight orby a spring, to the position to be cut off line by line by thepusher-bar B. This pusher-bar B, a partial longitudinal vertical sectionof which is shown in Fig. 9, is actuated, as is representedin Fig. S,byone or more coiled springs, S S S, one end of which spring is attachedto the shaft S at s, passing through them, and around which they arecoiled, and the other end thereof to the bar S It is clear from saidFigs. 8 and 9 that these springs may uncoil, rotating the shaft S. Onthis shaft is the geared wheel .l) ,whose gears mesh into gears cut inthe lower side of the pusherbarll, Fig. 8, and actuate it as the springsunwind. This movement of unwinding causes the bar B to advance, pushingbefore it in the channels 0 the line of type out off from the deadmatter in the galley A as the end letter is expelled by the hammer F.hen the bar B has advanced along the channel 0 to the limit of its rangeof movement, it is retract-ed along the channel C by the crank D, whichreverses the rotation of the shaft S and brings the bar B back to aposition to take another load of type and push it along, as has beenexplained. The stop C at the end of channel C prevents the type fromgoing beyond the desired recess in the receiver, the instant the hammerF has been withdrawn, as before explained, thus placing the final letterof the line in the channel C in such position that the hammer F upon itsrelease, forced by the spring F will drive this end type into the recessE of the receiver E. This receiver E,with its mate E, is, in fact, onlythe extension of the tubes P in Fig. 4, with the openings at theirsides, which form the recesses into which the type are forced by thehammer F. Down these tubes the type fall foot foremost by gravitythrough the tubes P and P into the channels N N. Each receiver carriesthe end of onehalf the tubes or channels required in this part of themachine. There would be sixteen or twenty, according to the number ofthe type of different kinds to be distributed that is, according to thesize of the case. I have found sixteen recesses or months suflicient forninety characters. Each machine would have but two receivers, one oneach side of the opening in whence the type issue. The explanation givenof the mechanism that moves one of these receivers applies eqnally tothe other, only they advance from opposite sides, and on receiving theletter called for by the key depressed withdraw from theopening inchannel C, through which the type are expelled in opposite directions,Fig. 4. This withdrawal is effected by the coiled spring E, Fig. 2,attached at one end to the frame A and at the other end to the receiver.This movable receiver, carrying, say, sixteen recesses or openings fortype, for receiving as many as one hundred and ninetytwo differentcharacters, is made as light as possible, so as to move easily andrapidly and with the least possible momentum. It may be suspended, asshown in Fig. 5, supported by and running on wheels 6, forming a kind oflittle truck which runs on track a a. As I have said, each one of therecesses or open mouths for the reception of type is but the extensionof a tube of some light material that can be put in such form that thetype as they fall foot foremost cannot rotate in their passage. Rubbertubes might be used, because, being elastic, they would allow thereceiver to move freely with slight impediment. I do not limit myself toany material for these tubes, nor to their being elastic; but I havefound tubes or channels of light coiled wire the best, as they are verylight and elastic and easily take the shape to adapt them to any size oftype that must pass through them, and are very durable, cheap, andclean.

0 is a piece which supports the lower end of the tubes P, as shown inFigs. 10 and 12. It is supported by the piece 0, as in Fig. 10, and isof such shape that the lower part of piece 0 which forms the end of thetubes P, fits snugl *between the two sides of said piece 0 as seen inFig. 12. As I use only these coiledwire tubes for conducting the typefrom the channel 0 to their final deposition in the channels N N N, Ishall speak of them hereafter as wire tubes, not intending thereby tosurrender my right to use tubes of any material suitable to perform thesame functions. The moment a key is depressed the receiver E or Epresents the appropriate recess or mouth to receive the type expelledand instantly retreats to its former position, ready to start again.Previous to this last movement in retreat to resume its position, whichcommences upon releasing the key from under the finger, the coiled-wiretubes P, which exert a pull upon it, act as springs to bring it back. Incase other than elastic tubes P are used a spring at E would be requiredto bring it to the proper position, as has alreadybeen explained.

The letter A of large and small capitals and lower-case and Italiccapitals and lower-case all enter the recess or mouth of the same tube.The same is true of all the Bs and all the Us, and so on for all theletters. These wire tubes, connected at the upper end with the receiverE or E, terminate at T, Fig. 3. To this point but thirty or forty tubeshave been used to pass down, say, one hundred and ninety differentcharacters. The distribution has been but partially effected. By thelower tubes, P, Fig. 3, it is completed. At the point T the upper thirt-two tubes leading from the removable receiver terminate. Ar-

ranged in gangs or rows corresponding in number with the tubes P aboveare one hundred and ninety-six rows, or a number to correspond with thesize of the case. These rows, whether two or six, are attached togetherfirmly at the upper part, so as to move together. Some one of the rowsso adj usted below the outlets of the tubes P above as to receive intothem the type as they fall is always accurately beneath the outlet ofthe tubes P. One row receives, say, the lower-case, another the largecapitals, another the small capitals, 850. Each of the thirty-two tubesP discharges into some one of the thirty-two channels N. At the lowerend of each of these tubes P is a small piece, 0 (shown in Figs. 12 and13,)

made to be easily attached to the wire tube by folding together thewings 0, which act as clasps, the lower part readily sliding into theshort fixed portion of the channel N.

Fitted in frames to support them are the removable channelsin fact, onlycontinuations of the short channels N, into which the type drop. Vihenthese removable channels are loaded or filled with type, they are takenaway to the setter and other empty ones substituted in their place to befilled in like manner. I will now proceed to explain how the lowertubes, P, are adjusted at pleasure beneath the upper tubes, P, so as toreceive the types as they descend, and the different type are selectedand delivered to the channels N.

In l at Q are shown five keys to the left and slightly below the keyboard. These keys are marked so as to indicate the row of the tubes Pwhich each key actuates. One brings under the tubes P the row ofthethirtytwo tubes P that receives the lower-case letters, another thelarge capitals, and so on for all the rows of the tubes P. These rowsmaybe so arranged that their normal position may be that the center rowwill always be below the tubes P unless otherwise determined on by oneof the keys Q, above mentioned; but in my drawings I have shown thenormal arrangement to be that one of the outside rows shall be standingunder the tubes P and the key Q serve to bring the others beneath thetubes P as required, the whole gang moving in one direction toaccomplish this. Fig. 7 shows the mechanism by which these movements areeffected. the levers Q fulcrumed at Q which levers at Q are connected byrods Q to arms Q which act independently of each other to slightlyrotate the shaft Q Attached to the shaft Q are the arms Q and Q that inFigs. 2, 3, and 7 serve to move the six gangs or rows of tubes P to theposition predetermined for each beneath the mouth of the thirty-twotubes to receive the kind of type indicated by the moving key Q in Fig.7. The normal position of these six rows of tubes is that one row, asexplained above, shall serve for the lower-case and mostused letters andthe depression of any of the five keys shall bring the gang of tubes Pto a position to receive from the tubes P the de- The key-heads Qactuate scending type called for and predetermined by the key depressed.Upon the release of the key Q the gang is returned to the normalposition by the action of coiled spring T At Q Fig. '7, is shown astair-shaped stop, which is fixed at its lower end to the shelf A andregulates the movements of the levers Q, and consequently, through theintervention of the yoke Q same figure, the movement also of the arms Qwhich move the gang of tubes P and determine which row thereof shall bepresented under the tubes P to receive the type at the will of theoperator.

The guard Q about the levers Q is firmly attached to the shaft Q andmoves freely up with the movement of any one of the levers Q, asdetermined by the movement of key Q. The stop Q limits the movement ofeach one of the levers Q, as has been said. This movement determines theangular movement of the arm Q which determines the position of the gangof tubes P. This large group of lower tubes, P, as shown in Fig. 2,continues down to the short fixed channels, one of each being devoted toreceive and hold the type coming down the tubes P and P, the faces ofthe type being all up and the printers nicks all on the same side, asthey must be in order to be properly set in the setting-macl'iine. Awhole row of these tubes P finds the channels to receive their typeranged on one shelf say the top one, as seen in Fig. 3 at V, the nextone at V, and the next one at V and so on for all. These tubes P as theydescend may be so spread and extended as to make all the channels Neasily accessible. The type when they arrive in channels N are kept ontheir feet by a small piece of metal, P that supports them on one side,while the pusher prevents their falling on the other, as shown in Fig. 3and enlarged in Fig. 12. This small piece of metal slides along thechannel easily before the type as they are shoved forward by the pusherO. \Vhen enough type has been delivered in this manner in any channel tofill it, it is removed to the setter and an empty one put in its place,with the small piece of metal, as beforesaid, in position. A spring, asshown in the central channel, Fig. 11, will answer the same purpose asthe slide. Unless there were some arrangement to advance each type as itarrives in the channel N, the next one coming would find no" place inwhich to stand, and would thus clog up the channels P, and thus bringthe operation of distribution to a standstill. At the upper end of thechannels LT are the hammers or pushers O O 0. (More clearly seen inFigs. 10 and 12.) Vhenever any key of the key-board G is depressed, onegang of these hammers (see Fig. 1) moves, so as to push forward a singletype in front of some one of them. I have made the hammers to operate ingangs rather than singly, in order to avoid multiplying parts and inorder that they may be made very light, and since there is only one typeto be moved at a time there is no difficulty in connecting them ingangs, as described.

The piece 0 contains as many openings P as there are differentclutracters to be distributed. These openings are fitted so accuratelybelow and close to the lower ends of the tubes P that the typedescending through the tubes P cannot fail to enter the row beneath.These openings P in the piece 0 are only the mouths of the tubes P. Ifthere are fifteen of the tubes P, there will be fifteen of the openingsP in a line. If there are twenty or thirty of these tubes, there will bea corresponding number of these openings in a line directly below them.Since there are, for instance, thirty of the tubes P, there will bethirty of the openings P in one line. To re ceive the one hundred andeighty different characters there must be then six of these lines. Ihave explained how this piece O is moved to bring any one of these sixlines of openings under the mouths of the tubes P at the will of theoperator, though I by no means confine myself to this number or anynumber of tubes in a row, being governed wholly by the number ofcharacters to be distributed in working. These six rows of tubes delivertheir contents into type-channels arranged on three tables or shelvesone above the other, as shown, though all might be delivered upon onetable. This present arrangement necessitates connecting all the tubes Pin two rows or lines at their connection with the piece 0 into one rowof type-channels on each of the tables or shelves. ing of these tubes,but in no wise interferes with the descent of the type. This upper shelfmight be so widened as to receive all the tubes P, or it might bearranged in a circular or curved form with all the type-channels on thesame table; but the arrangement as shown is more compact. It requirestwo rows or gangs of the tubes P to fill one tablethat is, if there arethirty in each row there will be on the table sixty channels to receivethe two rows of thirty each.

The channels N are made to incline from the point where the type enterthem, Fig. 12, in order that gravity may aid the pushers as the linebecomes long. The angle at which the channels N incline should be fromten to twenty degrees from a horizontal line. At 0 in Fig. 12 is shownthe manner of attaching and securing the piece 0 Fig. 13, to theextremity of the tubes P, and how it stands above the channel N todeliver its type B into the short channel below, and how the type infront as they fill the channel N are supported from falling forward bythe small piece P The same figure shows the position of the pushers O O0 ready to advance the type forward as they fall into their respectivechannels. A small section of these channels Nsay to 0 Fig. 12-is madepermanent, and the end of the removable portion simply slips over theend of the fixed part, which This compels a cross holds it in position,and thus the type as they advance run easily into it.

I will now proceed to show how the hammers or pushers O, that advancethe type as they fall into the channels N, are actuated.

In Fig. 15 at \V is seen an arm connected to the shaft M,which shaft ismoved as heretofore explained. This shaft, as has been said, has twofunctions. The first has been. described. To actuate the pushers is thesecond. At the extremity of this arm \V is seen the rod IV, to descendthrough the key-board. This rod is again seen in Fig. 7 at \V'. It isconnected at its lower extremity to the lever which is firmly attachedto a bar, W whose ends are so bent and shaped as to enable the rod thefulcrum of the lever to pass freely through and slide thereonlongitudinally, as well as to allow the free movement of the lever Thelever \Y is seen to be exactly over one of the levers V Now if the rodconnected with the rod at V moves up, as it will do whenever any key ofthe key-board is depressed, the opposite end of the lever is depressedat in Fig. 7. This depression of the end of lever depresses thecorresponding end of one of the three levers YVfiwhich lie directlybelowit and in close proximity thereto. The other end of \V consequentlyrises. This end is connected by the rod IV with the arm \V at \V inFig.12, which arm is rigidly connected with the shaft \V To this shaft thehammers O O O are also connected at such an angle with reference to thearm IV that the raising of the same by the rod connected at W will causea rocking movement of all the hammers on that shaft. This rockingmovement causes the hammers O O O to move through the angle large enoughto push forward any type in front of any one of them far enough to admitthe thickest typefor instance, the letter \V that enters any channelconnect-ed with that gang of hammers, and as this movement is given bythe depressing of every key of the key-board it will be seen that onlyone type is presented to be acted on at one time by any hammer.

It will be seen in Figs. 1, 3, and 7 that each gang of hammers has anindependent connection above with one of the levers \V. As the key Q inFig. 4 determines what gang of tubes P in Fig. 3 shall receive thedescending type, and what gang of channels N shall also receive them, sothe same'key determines what gang of hammers shall operate. The wholenumber of these hammers being great, they cannot all conveniently bemoved by each lever of the key-board at the same time, owing to theirnumber and consequent resistance.

In Fig. 7 is shown the mechanism used to move the lever over any one ofthe levers W lying beneath it. The rod X in Fig. 7 is supported on theunder side of the table or key board by a hinged joint at X This rod isa The and present the lever V over one of the levers hile in thisposition the depression of any key of the key-board will move the gangof hammers connected with any of the rods \V, described and designatedby its proper key.
